Vette is regarded as the form surfer of the division this summer and pundits feel he could snatch the series title with a big performance this weekend.
Conditions could be conducive to a special performance, with a forecast 1.5-metre swell and onshore winds expected to challenge competitors.
The young surfers could be inspired by the presence of 1999 world champion Mark Occhilupo and current Championship Tour surfer Ryan Callinan, who are in New Zealand on a promotional tour and will be at the finals tomorrow.
In the other divisions, Luis Southerwood (Whakatane) leads the u18 boys after two wins from two events.
Tao Mouldey (Mt Maunganui) leads the u14 boys' rankings.
In the girls' competition, Gisborne's Asia Braithwaite lies equal-third (with Anna Brock of Mt Maunganui) in an u16 field led by Natasha Gouldsbury (Taranaki), with Liv Haysom (Piha) second.
Georgia Wederell (Mt Maunganui) leads the u18 division, while Chloe Groube (Pauanui) leads the u14s.
